   Isn't it the way for things to happen, your display dies when you are the furthest away?

	Minis are doing the trick. Think I now know how that UAV went down in Iran! Mil-Spec - lowest cost, worst reliability.

	As for RS-485 chips, I've been happy with Maxim 13082E this year. They are not MIL spec, but I figured I would give them a shot since the recommendation which led me to them came from Canada. Michael

	So far keeping 200 watts of light (2 100W bulbs) attached to a thermostat and sitting on the side of the Q-Spot nearest the microcontroller is doing the trick at getting the Q-Spot to start up each day. When the show begins I turn off the "heater lights". During the night I have the channel set to be on for 10 minutes of every hour (minimal heating to prevent frost), and around midday I have the channel set to turn on continuous leading up to the show. The thermostat is set to 75F so once it hits that it starts cycling based on temperature. I have no idea why it became temperamental this year. In the past I've been able to start it up in single degree weather without any problem. Michael

	You tell me about temperature. One day it's misty, fog and rain and the next, 5 degrees below zero. These boxes then start behaving at their own discretion!
